The "Enterprise Accounting Standards" issued in2006standardized the corporate accounting recognition, measurement and reporting behavior. Ministry of Finance, the Securities and Futures Commission, the Audit Commission, the CBRC, the CIRC and other departments jointly issued the "internal control norms", in June2008; above-mentioned five ministries jointly issued the "internal control supporting guidelines" in April2010. These specifications provide a lot of guidance to establish a sound internal control.The decision usefulness is one of the most essential feature of the quality of accounting information. The quality of accounting information has a direct impact on the investment decisions and consequences of investors. In our country, however, it is an undoubted fact that many people worry about the quality of accounting information because it exists serious problems of accounting information distortion. How to improve the quality of accounting information has become an important subject in the theoretical field of financial accounting at home and abroad. Now, most of the scholars in this field agree with that:in order to improve the quality of accounting information, we must pay more attention to the internal control, whose validity and integrity to a large extent decide the quality of accounting information.On the basis of existed studies of scholars, considering the deficiency of current realities and researches, this thesis mainly focuses on the construction of internal control assessment system and the analysis of influence on the quality of accounting information by internal control, hoping to provide new ideas for related studies. This thesis consists two parts:the theoretical part and empirical part.In the part of theoretical analysis, as the first two parts in this thesis, on the basis of reviewing some researches of authorities and scholars at home and abroad, firstly, this thesis presents the relevant concepts of the internal control and the quality of accounting information and states their current situation and the reasons. After that, it puts forward the route of the influence on the quality of accounting information by internal control, and discusses the influence on the quality of accounting information by internal control from two perspectives of internal control elements and internal control objectives, providing the strong theoretical support for the raising hypothesis and the empirical research of this thesis. Finally, according to the theoretical analysis, it puts forward the hypothesis:internal control and the quality of accounting information have positive correlation in listed companies, which means the higher the internal control index, the higher the quality of accounting information.In the part of empirical research, as the three to five parts in this thesis, on the basis of the internal control assessment system based on objectives-orientation, the author selects2012Shanghai A-share listed companies as a sample. As earning quality substitute for the quality of accounting information for be explained variable, by extracting principal component from many internal control assessment indicators building internal control index as explained variable, using spssl9.0for regression analysis found that, the effective internal control can restrain the companies’ earnings management, improve the earning quality and improve the quality of accounting information.
